can you please help me with this please. thank you. A small mass m hangs at rest from a vertical rope of length l that is fixed to the ceiling. A force then pushes on the mass, perpendicular to the taut rope at all times, until the rope is oriented at an angle delta and the ...

A ball is attached by two spring as shown [vvvOvvv]. If the mass is displaced a distance △x BELOW the equilibrium position h (see figure A). Determine whether vertical SHM is possible for the system shown.If so, find the natural frequency. [Assume that the vertical extension...

You have a 120-g meterstick. Where should you place the meterstick atop your finger so it balances? Where is the balance point if you place an additional 100-g mass at the 20-cm mark and a 200-g mass at the 80-cm mark?

When an object of mass m1 is hung on a vertical spring and set into vertical simple harmonic motion, its frequency is 12 Hz. When another object of mass m2 is hung on the spring along with m1, the frequency of the motion is 4 Hz. Find the ratio m2/m1 of the masses. w= sqrt (k/...

Two blocks hang from strings going around pulleys of different diameter that are connected, as shown in the figure. The large pulley has a radius of R = 9.0 cm and and the small pulley has a radius of r = 2.3 cm. The mass of the block that hangs from the small pulley is m = 3....
